USING WAVEFORM MATH FUNCTIONS

You can perform several math functions on the various waveforms or memories.

•ADD, SUBTRACT, and MULTIPLY require two oper- ands (SOURCE 1 and SOURCE 2). The operands can be selected from acquisition memories or waveform memories.

•INVERT, INTEGRATE, and FILTER require one oper- and (SOURCE 1) from acquisition memories or wave- form memories.

•All operations require a DESTINATION waveform memory selection.

NOTE

Leaving the Math function active will cause a continuous update of the destination memory if the source(s) are active waveform(s).

1.Press to open the Special Functions menu.

2.Press to open the MATH menu.

3.Start or stop the math function by turning the MATH FUNCTION on or off.

4.The MATH OPERATION list box lists all math opera-

tions available. Choose one and press to select.

5.Use to highlight the source(s) and destination

items. Press to open the list boxes. Now choose

the source(s) and destination. Press to select.

Scaling the Display

The Scale factor allows you to adjust the display to

accommodate the math result. Use or to

highlight SCALE RESULT, and press to open the list

box. You can now use and to highlight: off, /5,

/25, or /125, and press to select.

Choosing a Math Operation

You can choose from the following six math operations:

Add Adds two waveforms (each sourced from an active input or a memory location) and stores the result in a waveform memory. For example, waveforms from INPUT A (SOURCE 1) and Waveform 1 (SOURCE 2) can be added, resulting in a waveform stored in Waveform 4 memory (DESTINATION).

Subtract Subtracts the SOURCE 2 waveform from the SOURCE 1 waveform and stores the result in the next free waveform memory. As with ADD, active inputs or memory locations can be used in any combination for the sources.
